APPARATUS FOR INJECTING SOLID VACCINE MATTER.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed January 25, 1906. Serial No. 297,808.

To (LN, whom it may concern:

Be it known that I, HIPPOLYTE DEFER- nUssIN, a citizen of the FrenchRepublic, residing at Paris, in the Department of the Seine, France,have invented certain new and useful Improvements in Apparatus forInjecting Solid Vaccine Matter, of which the following is aspecification.

This invention relates to an apparatus for injecting underthe skin ofanimals a vaccine matter in the solid formpills, for example.

This invention is shown in the drawings accompanying the presentspecification, in which- Figure 1 is a vertical cross-section. Fig. 2 isa cross-section of a modification of same apparatus. Fig. 3 is a planview of the feeder.

This apparatus consists of two parts: first, the device by means ofwhich the vaccine matter in the solid form (pills,for example) is drivenin under the skin of animals; second, the feeder containing the vaccinematter in the solid form.

The present specification will refer to vaccine matter used in the formof pills, but it is evident that the present injecting apparatus, whichforms the subject of this invention, may utilize any other appropriateform of solidified vaccine matter.

The device allowing the operator to drive in or throw the vaccine matterunder the skin of animals may be of any appropriate type, and the onehereinafter described is only given as an example. This device consistsof a metallic tube 1, closed, at one end by a stopper 2. which isprovided in its center with a hole, so as to permit the stem or rod 3 topass through. At the other end is situated the feeder A, which is sodisposed as to present at a proper place and in front of the extremityof the stem 3 the pill to be ejected. In the tube 1 works the stem 3,whose action is to throw or eject the pill out of the apparatus.

The device is set for action by pulling back theknob 5 till the groove 6of the said stem comes into contact with any kind of catch 7, fittedwith a small spring 8 and a pushbutton 9. a guide for the stem 3. A mainspring 10 gives its propulsive ower to the stem 3 and is compressed bypu ling back the knob 5.

This catching device'also acts as Once the device is set, it can bedischarged by pressing the push-button 9, whereby the catch 7 isdisengaged from the groove of the stem 3, which being violentlypropelled through the strained spring 10 its extremity 11, buttingagainst the pill 12, which is presented by the feeder at the openingleft for the purpose in the axis of the tube, forcibly ejects said pillthrough the hollow needle 13, situated at the extremity of theinjectingapparatus.

The feeder is a flat notched barrel or disk 4,- provided with a cover15, either of transparent material or otherwise, which is free to moveround an axis 16. The barrel is provided with a plurality of holes 17,ineach of which a single pill can be received. A small plate 18, situatednear the opening communicating with the hollow needle 13, is secured tothe wall of the feeder and extends or covers a few holes (three, forexample) of the barrel, so that the holes of this latter,

.each filled with one pill, pass successively before the openingcarrying one pill at a time into line with the stem 3. This plate 18,which is secured in place, prevents two or more pills coming at the sametime and obstructing this said opening, which is made for one pill aloneto pass.

By revolving the barrel a certain number of notches each hole filledwith one pill will pass successively before the opening situated in theaxis of the hollow needle 13.

The operation is as follows: The feeder 4 is uncovered by turning thedisk 15 around its axis 16. It is not necessary to take the pills one byone nor to touch them, simply pour them in until the feeder is full. Afew pills immediately fill up the holes 17 of the barrel, the bottom ofwhich is formed by a plate 19, preferably integral with the tube 1, andconsequently not revolving with the barrel. Once the pills are pouredinto the barrel the disk 15 is replaced over the feeder 4 and is kept inthat position by screwing down tightly the hollow needle 13 or by fixingit by any other convenient means. The feeder being ready the stem isdrawn back until engaged by the catch 9 in the same way as has beendescribed hereinbefore. When the barrel (which alone is made to revolve)is turned by a few notches from right to left, a small spring 20, fixedupon the tube 1, presses against the notches on the side of the saidbarrel, thus preventing it from turning back and allowing it .to beplaced in such predetermined position that the holes will exactly comeinto line with the axis of the hollow needle. Before the firstinoculation it is necessary to turn thebarrel three notches, this, ofcourse, if the plate 18 covers three holes. The first pill is then inthe axis of the needlethat is to say, ready to be injectedas it is shownin Fig. l. The point of the needle being sterilized, itis introducedthrough the skin of the animal at the desired spot and the push-buttonis pressed. The stem 3 is disengaged all at once, the spring expandingcauses the extremity 11 of the stem to butt against the pill, which ispropelled out of the apparatus, passing through the hollow needle 13under the skin of the animal. The stem 3 afterward occu pies theposition shown in dotted lines. For the second inoculation the stem 3 isagain drawn back, the barrel is turned one notch, bringing the secondpill before the opening of the needle, this latter being againsterilized and introduced under the skin of another animal, thepush-button is pressed, and the second inoculation is effected, so onfor the following operations. Such an apparatus of usual type maycontain about a hundred pills in the feeder. The advantages in usingthis apparatus will be clearly understood if consideration be given tothe conditions of inoculation practice and the rapidity with which theseoperations may be accomplished.

The extremity 11 of the stem 3 may come either at the opening of thebarrel contain ing the pills to be ejected, as shown in Fig. 1, orpursuing its course pass inside the hollow needle to occupy the positionshown in dotted lines in the Fig. 2, which is a modification of the sameapparatus.

It is evident that the device for throwing the pill out of the apparatusn:ight be quite different from the one given herein as example withoutchanging a single particle of the principle of the present invention,which consists in placing agreat number of pills in a feeder andintroducing these under the skin of animals in combination with thethrowing or ejecting device of any appropriate type. As another example,the disposition herein described may be exchanged for a device similarto that employed in the firearms called revolver.

Having now particularly and fully de scribed and ascertained the natureof my said invention and in what manner the same is to be performed, Ideclare that what I claim is l. A device for inoculating animals withsolid vaccine matter, comprising a handle,

a hollow needle, a stem working in the handle and needle, a springadapted to be compressed when the stem is drawn back, a catch forengaging with the stem when retracted, and means for teeding the vaccineinto line with said stem.

2. A device for inoculating animals with solid vaccine matter,comprising a handle, a hollow needle thereon, a stem working in thehandle and needle and having a notch, a spring adapted to be compressedwhen the stem is drawn back, a spring-catch to engage with said stemwhen retracted, alidmeans for feeding the vaccine into line'with saidstem.

3. In a device for inoculating animals with solid vaccine matter, thecombination with a hollow needle, of means for ejecting the vaccinematter therethrough, and a feeder for said matter comprising a rotatableelement having holes for the vaccine matter and so mounted as, whenrotated, to bring said holes in line with said needle.
